Advertisement: When your car's engine is running at its normal operating temperature, any major brand of motor oil will protect it about as well as Tuff does. When the engine is cold, it is a different story: Tuff motor oil flows better at lower temperatures than its major competitors do. So, it you want your cars engine to have maximum protection, you should use Tuff.

Which of the following, if true, most strengthens the argument in the advertisement?

(A) Tuff motor oil provides above-average protection tor engines that happen to overheat.

(B) Tuff motor oil is periodically supplied free of charge to automobile manufacturers to use in factory new cars.

(C)Tuff motor oil's share of the engine oil market peaked three years ago.

(D) Tuff motor oil. like any motor oil, is thicker and flows less freely at cold temperatures than at hot
temperatures

(E) Tuff motor oil is manufactured at only one refinery and shipped from there to all markets.

Conclusion: If you want maximum protection, use Tuff motor oil.
Premise: Tuff offers no better normal temp-protection than its competitors, but it offers better cold protection.

So we know that Tuff is roughly equivalent to its competitors at normal temperatures. We know it's better at cold temperatures? Well, what about hotter temps? If Tuff works great in the cold, but can't protect the engine against overheating, it's clearly not going to confer the best protection. This is what A addresses.
